UWS400SA Ultrasonic Welding Machine

Product Description

Programmable ultrasonic welding machine with standing post-bed version

The workpiece is held between the sonotrode and the anvil wheel and welded continuously under pressure. When welding continuously by the ultrasonic method, the material to be welded will be subjected to rapid changing pressure vibrations. The heat develops because of molecular vibrations beneath the material surface, for thin materials within the immediate vicnity of the actual weld.

Ultrasonic welding with the UWS400SA is a modern, innovative and economic altemative and complementary to conventional sewing technology If assembling of laminates, clothing fabrics with high share of polymer and technical nonwovens is required and in particular to get, the use of the UWS400SA is the first choice.

Features

• Controled electronically (power. amplitude, speed and pressure)
• Seam distances resp operating cycles can be programmed
• Reproducbility of the welding process
• The energy adjusts to the speed (via a pedal), so that reliable dynamic welding
• Equpped with differential feed separate drive for sonotrode and anvil wheel thatmeans smooth, non-dstorted seams or the pssibility of adding a some fullness
• Process reliability through monitoring of welding parameters with integrated device tor constant peformance, so that reliable processing is pssible even when sewing over cross searms
• Possibility of spot welding (tacking)
• No start/stop – marks
• Touch screen (simple handling with pictograms).

Application

The version is particularly well suited for welding three-dimensional shapes, such as hoods, caps, bags, etc. With the aid of the column two parts can be joined together flat.
In this process the part is placed around the column and then welded from the column out (e.g. the longitudinal seal of a sleeve or of a filtering bag, processing of hoods, covers).
